Abstract
An apparatus and method for controlling noise caused by vibration in a camera module for a mobile device are provided. The method includes transmitting a vibration signal sensed by a vibration sensor to a Choice Coil Motor (VCM) driver based on the vibration signal, applying, by the VCM driver, a reverse bias to a VCM upon receiving, by the VCM driver, the vibration signal from the vibration sensor, and exerting, by the VCM to which the reverse bias is applied, an electromagnetic force in a reverse direction in order to fix and halt an actuator.
